Peter I of Hapsburg (1602-1633) was the King of Scotland and Czar of Russia after the death of his father William II. He, like his father William, was heir to the vast domains of the ageing Henry IX, his grandfather. However, he would not become heir to these domains because of his death in 1633 two years before his grandfather. The domains would instead pass to Peter's 14-year old son, Alexander. During his reign he had difficulty ruling over both Scotland and Russia, which had two very different cultures. He more often preferred to stay in Russia, where his reign successfully concluded the period of Russian history known as the troubles. He married Elisabeth Bourbon of France in 1621.
